TRIUMF Research Scientist


Isabel Trigger graduated with a B.Sc. from McGill in 1994 and went on to complete an M.Sc. and a Ph.D. at the Université de Montréal between 1994 and 1999. Her M.Sc. thesis, “Evolution du spectre de dépôts énergétiques dans les détecteurs au silicium irradiés en protons,” studied the ultimate performance of silicon-based precise tracking detectors in the presence of radiation for the LHC. Her Ph.D., “Mesure des couplages trilinéaires anomaux des bosons de jauge avec le détecteur OPAL au LEP,” included definitive measurements of the self-coupling of standard model gauge bosons and is considered one of most challenging experimental analyses performed at the Large Electron Positron (LEP) Collider.

Dr. Trigger was awarded the competitive CERN Research Fellowship in 1999, leading to the exceptionally rare offer of a CERN research staff position in 2001. She personally performed the most general and comprehensive search for the “chargino” particles predicted by supersymmetric theories.

Isabel was also a leader in the CERN team designing and testing the alignment system that monitors the relative positions of the 22 m diameter ATLAS endcap muon chambers with 50 μm accuracy. In 2005, TRIUMF recruited Dr. Trigger to lead the establishment of an ATLAS physics analysis group.
